attribute NC_GLOBAL summary String This data archive contains quality controlled data from BGC-Argo floats deployed by the Southern Ocean Carbon and Climate Observation and Modeling (SOCCOM) and Global Ocean Biogeochemistry Array (GO-BGC) projects. Data for all floats within this archive were processed by the float data management team at the Monterey Bay Aquarium Research Institute (MBARI). This dataset contains the latest available snapshot archive. Each snapshot archive is assigned a unique DOI, and is hosted on the SOCCOM UCSD library digital collection. All snapshot archives of this dataset are available through the full GO-BGC & SOCCOM joint UCSD library digital collection.See the DOI and history attibutes for specific references for this snapshot. Float specific metadata, as well as raw and QC files from the near-real time dataset are available at https://www3.mbari.org/lobo/Data/FloatVizData/ (external link) (navigate to the /QC/ subfolder for quality controlled files). BGCArgo formatted netCDF files for the SOCCOM array are also available on the Argo GDAC (https://usgodae.org/pub/outgoing/argo/dac/aoml/) (external link). NOTE: While delayed-mode quality control (and data adjustments based on comparisons to reference fields) is assessed across the array prior to the generation of each snapshot archive, all data is PROVIDED AS-IS. Be aware that INACCURACIES MAY BE PRESENT within the data. SOCCOM data managers do their best to provide high-quality, complete data but make no guarantees as to the presence of errors within the data itself or the algorithms used in the generation of derived carbon parameters. It is the USER'S RESPONSIBILITY to ensure that the data meets the user's needs.

K1 and K2 dissociation constants were from Lueker et al., 2000, doi:10.1016/S0304-4203(00)00022-0. The KSO4 dissociation constant was from Dickson, 1990, doi: 10.1016/0021-9614(90)90074-Z. The KF dissociation constant was from Perez and Fraga 1987, doi: 10.1016/0304-4203(87)90036-3. The borate to salinity ratio was from Lee et al., 2010, doi:10.1016/j.gca.2009.12.027. Silicate and Phosphate were not measured by the float, but estimates based on Redfieldian ratios improved the carbonate system estimates. If a nitrate value was considered to be of good quality silicate = nitrate*2.5 and phosphate = nitrate/16, otherwise the best estimate for both was considered to be 0. When pCO2 was estimated from TALK_LIAR and pHinsitu, a bias was first added to pH (25C,0dbar) following Williams et al., 2017, doi: https:doi.org/10.1002/2016GB005541 , section 3.4, equation 3.

attribute DIC_LIAR comment String NOTE THAT THIS IS A DERVIED PARAMETER; VALUES HAVE NOT BEEN DIRECTLY MEASURED. DIC_LIAR values are estimated from pH_insitu and TALK_LIAR using CO2SYS for Matlab. Note that TALK_LIAR was estimated using the Locally Interpolated Alkalinity Regression (LIAR) v2 from Carter et al., 2017, https://doi.org/10.1002/lom3.10232 (external link). All carbonate system variables calculated with CO2SYS for Matlab (Sharp et al., 2020; see also Lewis and Wallace 1998) used the following conditions: pH was reported on the total scale. K1 and K2 dissociation constants were from Lueker et al., 2000, doi:10.1016/S0304-4203(00)00022-0. The KSO4 dissociation constant was from Dickson, 1990, doi: 10.1016/0021-9614(90)90074-Z. The KF dissociation constant was from Perez and Fraga 1987, doi: 10.1016/0304-4203(87)90036-3. The borate to salinity ratio was from Lee et al., 2010, doi:10.1016/j.gca.2009.12.027. Silicate and Phosphate were not measured by the float, but estimates based on Redfieldian ratios improved the carbonate system estimates. If a nitrate value was considered to be of good quality silicate = nitrate*2.5 and phosphate = nitrate/16, otherwise the best estimate for both was considered to be 0. When pCO2 was estimated from TALK_LIAR and pHinsitu, a bias was first added to pH (25C,0dbar) following Williams et al., 2017, doi: https:doi.org/10.1002/2016GB005541 , section 3.4, equation 3. This correction is not necessary for DIC and DIC is computed with the reported pH and the TALK_LIAR value.
